Stop-motion series featuring Rastamouse, Scratchy and Zoomer, crime-fighting special agents who solve mysteries and play in a reggae band. The annual Mouseland Choir concert is coming up, and the president has an emergency - his Aunt Janessa is supposed to be performing a special number, but she isn't answering her phone. When the Easy Crew arrive at Aunt Janessa's house, she has lost her voice! Rastamouse's ginger and lemon tea seems to have done the trick, until the next day when she loses her voice again! While Scratchy and Zoomer give the president some singing lessons in case he has to step in, Rastamouse thinks up a plan to find out why Janessa keeps losing her voice.
